FOUR-HORSE EVENER FOR GANG-PLOWS.

SPECIFICATION forming part of Letters Patent No. 694,610, dated March4.-, 1902. Application led January 16, 1961. Serial No. 43,498. (Nomodel.) s

To all whom it may concern: y

Be it known that we, JOHN W. BROWN and GEORGE ELIOK, citizens of theUnited States, residing at Quincy, in-thecounty of Adams and State ofIllinois, have invented certain new and useful Improvements in Four-Horse Eveners for Gang-Plows, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,forming part of this specification.

Our invention relates to a four-horse evener adapted for use inequalizing the draft of four horses when attached to gang-plows.

Our invention has for its object to centralize the line of draft withrespect to the series of plows in gang and place said line of draft at apoint to one side of a position between the two innermost of the fourhorses, so'as to cause the proper equalization of draft in order tocause the horses to move and work in uniformity.

Gang-plows as now Yconstructed are subject to objection by reason of aserious difcultyviz., lack of room for the four horses attached to theplow; and especially the horse that works in the furrow, so that thehorses are crowded together in working. As a rule the furrow-horse iscontinually crowded out of the furrow onto the plowed ground by thetraces of the harness, owing tothe uneven draft present. In the.construction of our evener we have produced a proper arrangement andassemblage of parts that effectually overcomes the objectionable featureof such crowding of the horses. v

Our invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims. Y

Figure I is a plan view of our evener applied to a gang-plow, partsbeing broken away and shown in section. Fig. II is an enlarged detailperspective view of the two, levers of the evener with the upper one ofthe pair of plates to which the levers are pivoted partially removed.

1 designates the frame of a gang-plow, 2 and 3 the plows, and 4 and 5the plow-beams. 6 designates two plates, one of which surmounts theother. The plates 6 receive the pivotal connection of the plow-beams 4and 5 by means of pins 7, that pass through the `provided with arearwardly-extendiu g arm 10,

to which more particular reference will be hereinafter made. VIn theouter end of the lever 8 are a series of holes 11, either one of whichis adapted to receive a bolt 12 of a coupling 13, connected at itsopposite end to a doubletree 14, that carries a pair of singletrees 15.i The series of holes 11 provide for the adjustable application of thedoubletreecoupling to the lever 8, according to require- 16 designates ashort lever, the inner end of which is mounted between the plates 6 nearAtheir forward edges and which is pivotally connected to said plates bya pivot-pin 17, positioned approximately in line with the pivot of thelong lever 8. The lever 16 is provided with a rearwardly-extending arm18, that is of less length than the arm 10 of the long lever 8. The arms10 and 18 of the long and short levers, respectively, are connected by alink 19, the ends of which are pivotally joined to said arms by pins 20.The outer end of the short lever 16 is provided with a series of holes21, either of which is adapted to receive a bolt 22 of a coupling 23,that connects the doubletree 24 to the short lever 16, similar to themanner of the connection of the doubletree 14 to the long lever 8. Thedoubletree 24 carries singletrees 25.

In the use of our evener two horses are attached to the long lever 8 byits doubletree and singletrees, and a second pair of horses are attachedto the short lever 16 by its doubletree and singletrees. The greatestleverage in the evener would naturally be con.

tained by the long lever 8 if the two levers were of uniform dimensionsat their inner ends; but in the operation of our evener con structed asdescribed the excess of leverage in the long lever is counteracted bythe varyi ing dimensions of the arms carried by the two levers at theirinner ends. It will be seen ment in obtaining the proper draft on saidlever.

that while the lever 8 is longer than the lever 16 the arm 10 of saidlever is also longer than the arm 18 of the lever 16 and that thedistance between the pivot 9 of the long lever and the connection of thelink 19 thereto is greater than the distance between the pivot 17 of theshort lever and the connection of the link to the arm of said lever. Asa consequence the increased leverage of the long lever 8 over that ofthe short lever 16 is overcome by the increased leverage of the arm ofthe short lever upon the arm of the long lever, so that the leverage isentirely balanced, and the line of draft is centralized, with respect tothe plows arranged in gang, in such manner that the horses are caused topull evenly and exert a draft that is central with relation to theplows.

The dotted lines seen in Fig. I indicate the furrow made in theoperation of the plow, and in the use of our evener the furrow-horse ispermitted to constantly walk in line with said furrow, there being noliability of his being crowded therefrom by reason of unequal draft.

We claim as our invention- 1. In a four=horse evener, the combination ofa pair of plates separated from each other, a pair of leversindependently pivotally mounted between said plates, and means ofconnection between said levers, substantially as described.

2. In a four-horse evener, the combination of a pair of plates separatedfrom each other, a pair of levers independently pivotally mountedbetween said plates and having rearwardlyextending arms, and aconnecting -link by which said arms are joined between said plates,substantially as described.

3. In a four-horse evener, the combination of a pair of plates separatedfrom each other, a pair of levers, pivot-pins located in said plates andpassing through said levers to connect them independently to saidplates, rearwardly extending forked arms carried by said levers andpositioned between said plates, and a link pivotally mounted within theforks of said arms, substantially as described.
